My Comments

As the hype builds up about the “Internet Of Things” where devices can use a heterogenous network for exchanging data or receiving commands, there is oomething that can easily go wrong here. This is where particular vendors see the “Internet Of Things” as being the “Internet Of Things Around Our Products”, something that can stifle competition and, especially, innovation.

But steps have been taken towards creating a truly heterogenous Internet Of Things which is similar to what has happened with Bluetooth and Wi-Fi wireless technologies. Here, it involved the creation of industry-based multiple-vendor alliances who put forward what is required for all devices working to a technology to communicate with each other.

The Linux Foundation have set up the AllSeen Alliance in conjunction with Qualcomm with their AllJoyn protocol which was just lately made “open-source”. The goal is about implementing heterogenous transport layers that work without need for Internet connectivity and work in a vendor-independent manner.

At the moment, they are working on modular services that look at the following functions: discovery, pairing / set-up, message routing, and data security. THis will include proper user interface requirements including a rich user experience with the Internet of Things; along with an application-specific requirement  for streaming audio over many connected speakers.

There will still need to be an effort to assure secure interoperability on a function-based level so that a system based on units from different vendors can work as a system rather than having he need for software or hardware function bridges to allow devices of one manufacturer to work with those of another.

Once this happens, this can allow the Internet Of things to be affordable for most users and be a breeding ground of innovation.

In-room AV connection panel at Rydges Hotel Melbourne

A feature that is starting to appear in an increasing number of hotel rooms is the AV connection panel. Sometimes known as a “jack pack”, ”media panel”,  “aux panel” or something similar, these are wall-mounted connection panels or connection boxes located near the TV which provide a simplified way to allow you to connect your portable computing equipment to the TV and make use of it as a display and amplified speakers.

Here, these panels are a way to provide a “walk-up” method for guests to connect their technology to the TVs while the TVs remain anchored in place on the wall or in the cabinet. It also avoids the need for guests to grope around the back of the set to find the appropriate connections and risk unplugging existing equipment or plugging something in the wrong hole, which can cause an unnecessary maintenance request. This is in response to guests “bringing their own content” with them and wanting to view it from their gadgets on the large-screen TV in the room rather than watching regular TV or pay-per-view movies.

I have used one of these when staying overnight at Rydges Melbourne to connect my Galaxy Note II smartphone to the TV’s speakers to play music that is held on the smartphone. Here, this is a wall-mount panel that is equipped with RCA and S-Video sockets for stereo audio and analogue video, a VGA input and a 3.5mm audio input for computers alongside an HDMI input for most of the recent crop of laptops and other video equipment. There is also a USB “plug ’n’ charge” socket where you can connect your smartphone or other gadget to charge it. As I had previously mentioned, you can use the 3.5mm audio-in jack to connect your smartphone or other personal-audio device to amplify it through the TV’s speakers.

This particular setup has you selecting the different inputs as though they are “virtual channels” where you enter a particular channel number to select that input, similar to how some TVs and video recorders had you select a particular channel number to use the video inputs. Here, these “virtual channels” are listed on a reference card that is usually kept on the desk near the media panel. But some setups may have you use an “input” or “source” button to select these inputs.

If you are playing an audio device, you will find that the TV will show the blue screen and a reference to that channel as a way of showing that the selected input is working.

Who would benefit from these setups?

Laptop / notebook computer users

Connecting your laptop or notebook computer to the TV via the media panel’s HDMI input or, for older laptops, the VGA input for display and 3.5mm audio input for the sound, can open up increased functionality for these computers.

If you use the Internet service provided by the hotel, you can take this further by playing online media services like “catch-up TV” / video-on-demand services through the big screen. You also have the same benefit when you play video files that exist on your computer’s hard disk or use an integrated or USB-connected optical drive to play DVDs and Blu-Ray discs.

Those of you who like to play games on the laptop as a form of relaxation can benefit from the hotel room’s TV serving as a large screen for that game. It would be something that could impress business associates who do like to see these games as a way to rest between delivering those presentations.

Speaking of which, the large screen can come in handy for reviewing that presentation you have to give so you can be sure the graphics are in the right place and that each slide doesn’t look too overcrowded or dull. You are also at a better position for seeing the presentation from how your audience would see it. It is also a good chance to “dry-run” that multimedia presentation that you are running on your laptop so you are sure it is going to go to plan without things going wrong.

Similarly, the large screen will earn its keep with consumer and business videoconferencing applications like Skype, Viber and Facebook Messenger, especially those written for desktop (regular-computer) operating systems. Here, you can see your correspondent’s face on the large screen and hear your correspondent’s voice through the better-sounding speakers which may make their voice easier to understand. It is becoming more important as newer better audio-video codecs are taking advantage of increased available bandwidth to provide a clearer easier-to-understand voice.

Tablet and smartphone users

If your tablet or smartphone has an HDMI or composite video output, you can benefit from the TV being a large screen for these devices when it comes to gaming or playing online or stored video content. Here these devices will most likely use an MHL jack which works with these panels if you use an MHL-HDMI active patch cable. Older smartphones may also use the 3.5mm headset connector as a video / audio output and you would need to use a 3.5mm – 3xRCA breakout cable to play composite video from these smartphones.

As well the TV can simply serve as amplified speakers for these devices simply by you connecting the 3.5mm audio-input jack on the panel to your smartphone’s or tablet’s headphone jack using one of those 3.5mm plug-3.5mm plug cables..

Digital still and video cameras

You can preview your still images or footage you have taken on that large screen if your camera or camcorder has an HDMI or composite video output. Most of the recent digital cameras will implement a “mini HDMI” connector and/or composite video output via a 3.5mm multi-conductor jack due to their low-profile design.

The benefit you have with this is that it makes it easier to have “many eyes” looking for imperfections in the images and footage you have taken or have the benefit of a large screen to review those images or footage more easily. Even the speakers built in to these TV sets would do rings around the cameras’ integrated monitor speakers

Other personal audio and video players

Those of you who use portable DVD players or portable media players can have these devices play through that large screen in your room as an alternative to what is available on the pay-per-view movie service.

Similarly, your iPod Classic, MP3 payer, Discman or other legacy-media personal player (think cassette or MiniDisc) can benefit from being able to be played through the TV’s speakers with a louder sound. If you are using a handheld “note-taker” recorder, whether tape-based or digital, the TV speakers may allow you to hear the recording of that meeting that you made more clearly compared to the small integrated speakers that these recorders have. This could allow you to hear the muffled or soft voices, the voices with hard-to-understand accents or the distinctly-important background sounds more clearly.

Tips to get the most out of these connection panels

• Keeping a supply of cables handy
  A good practice to gain advantage from these media panels is to keep a supply of cables with you when you travel. These should allow you to connect your gadgets either to 3.5mm stereo jacks or RCA jacks for audio or HDMI, S—Video or RCA composite video for video applications. A good starting point when it comes to smartphones is my article on “essential smartphone accessories” where I mentioned about making sure you are equipped with a 3.5mm-2.5mm stereo patch cord along with a 3.5mm – 2xRCA patch cord for your smartphone’s audio needs.
• What sound playback device is this
  

  The HDMI input’s audio function serves as its own soundcard

  Laptop users who use the HDMI connections on these media panels will find that the HDMI audio connection is enumerated as a separate sound device like Intel Display Audio. Here, they may have to use the Sound Devices option in their operating system or application to direct the sound through the TV’s speakers with this connection.
  With the newer builds of Windows 10, you can set things up so that the multimedia apps like Spotify, Netflix or your media-player application can put their sound through the HDMI output while the default Windows Sounds comes through your laptop’s integrated speakers.

• Avoiding distorted sound through the TV speakers
  To avoid distorted sound from these setups especially if using the RCA or 3.5mm connections, adjust the sound volume at your source device to 75%-90% volume level and turn off any equalisation or sound-processing on the device if the device or software has this kind of adjustment. Here, you could get by with turning your device up to maximum volume and backing the device’s volume adjustment off slightly to set the input volume. Then you adjust the sound volume to your taste or programme content using the TV’s remote control. Some mobile devices implement a “Line-out” mode which bypasses all tone controls and sets the device’s output level to a nominal level so it works with external amplification.
• Setting up effective wireless operation
  

  A Bluetooth audio adaptor can allow you to wirelessly play the music on your smartphone or tablet from your bed or armchair

  You can set up a level of wireless operation with these media panels using an A2DP-compliant Bluetooth audio adaptor for music from your Bluetooth-capable laptop, smartphone or tablet; or a Wi-Fi-Direct-based Miracast adaptor for audio and video with Miracast-compliant laptops and Android devices.

• What are the channels to select for your equipment when you stay at that hotel?
  If you are a regular guest at a particular hotel, it is a good idea to make note of the “virtual channels” used for particular device connections in your travel notes if the setup you use takes this approach. This is more so as you bring particular gadgets, especially newer gadgets, on to the scene when you travel.

Update Note: (7 December 2018) I have updated this article due to myself upgrading my PC to Windows 10 April Update (build 1803) which has the ability to redirect sound output based on the software you are using. As well, through further knowledge of audio drivers supplied with computer graphics infrastructure, I have made a better reference to these drivers as well as a newer article about them.

Drosselkom: Telekom-Tarife: Wo Sie Flatrates und wo eine Drosselung bekommen | 02.12.2013 | Technik | news.de

My Comments

Previously I had touched on the issue of government involvement with providing competitive telecoms and Internet service. This was more about assuring that incumbent operators aren’t being given an unfair advantage over competing operators and is a situation that is happening in the USA but also happening in Germany.

In the USA where cable-TV companies and incumbent telcos in areas where there isn’t much in the way of competitive Internet service, the customers are being given an increasingly raw deal and are starting to face volume-limited tariff charts in a similar vein to what is happening in Australia and New Zealand and also what happens with mobile-broadband services.

Germany is facing an Internet market where their telecommunications regulator, Bundesnetzagentur (BNetzA), is being too favourable with Deutsche Telekom who is the incumbent telecommunications provider in that country. But there are not as many competitors in the telecoms and Internet-service space and they aren’t operating on a level playing field to what Deutsche Telekom is operating on.

What has been happening there is that Deutsche Telekom who were previously offering “flat-rate” Internet packages are moving towards similar packages to what is offered in Australia where there is bandwidth throttling and volume-driven packages. This has caused Deutsche Telekom to end up being called “Throttle-Kom” (Drosselkom) and there is consumer-law-based litigation taking place in some of the states (Lander) concerning breach of contract in relation to the “flat-rate” services.

Personally, I would like to see this also looked at by the European Commission in relation to a required level of competition for telecommunications and Internet services in built-up areas especially if Germany is to seek EU aid for communications projects. Similarly, German government departments at both the federal and state (Lander) level who have responsibility concerning competition and consumer issues need to have the country’s telecommunications and Internet-service market looked at.

Over the last decade, France and the UK have taken steps to assure competitive telecom service including Ofcom (UK’s telecoms regulator) hauling British Telecom over the coals to have them provide competitive access to the local loop at reasonable prices. This has been because the telecommunications regulators and the competition / consumer regulators have had real teeth and didn’t curry favour with particular operators.

If a country needs a lively Internet and telecommunications market where everyone can have access to a quality service at affordable prices, the telecoms regulators in that country need to work the market on a level playing field. Here, they cannot let incumbent telecoms and cable-TV operators run amok or apply double standards between incumbent and competitive operators.

Upcoming USB Type-C connector won’t have “right” and “wrong” sides | Gizmag

From the horse’s mouth

USB Promoters’ Group

Press Release (PDF)

My Comments

USB data / power cable to be eventually replaced with the USB Type-C data / power cable with the same plug each end

A new USB equipment connector is in the process of being designed and will be called by the USB Promoters’ Group by the middle of 2014. This is to cater for technology equipment that is becoming smaller and thinner while also allowing for quick worry-free connections.

This connection will be the same size as the existing USB Micro-B connector used on most smartphones or the Apple Lightning Connector that Apple uses on their latest iDevices. This will cater for devices that are acquiring an increasingly-low profile such as the smartphones, tablets or Ultrabooks or even peripherals like some external hard disks and keyboards.

The socket will be designed so that you don’t worry about which way you plug it in and the patch-cords will have the same connection on each end so you don’t have to worry about which end of the cable you are using, in a similar vein to the RCA connections used on most stereo equipment.

Of course, the standard will also define the patch cables that allow you to connect equipment that has the USB Type-C socket on it to equipment that has commonly-available USB connections like the Type A found on computers and USB power supply equipment or Micro-B connections found on the smartphones or USB hard disks.

As we are seeing the USB connection become the universal power-supply connection for many different gadgets. Here, the USB Type-C connection will also allow for scaleable power-supply and charging situations and to provide further support for improved USB bus performance. A commonly-raised question that could surface is the power-supply performance for particular USB patch cables especially as we find smartphones not charging as quickly with some cables compared to others given the same power-supply equipment.

Of course, this will cause a requirement for power-supply standards for mobile devices to be revised because of the current standard supporting only the Micro-B connection on the mobile equipment and Type-A on the power-supply equipment. As well, we will be ending up with USB Type-A to Micro-B and USB Type-A to Type-C as power/data cables for most of our gadgets in the near term.

Quality is now part of the games experience on these computers

A major part of the personal computer’s history has been about integrating the playing of games on these computers and every personal-computer platform had ended up with many different game titles available in a retail context or, in some cases, available for download. This has been the basis for heroes like Leisure Suit Larry and Carmen Sandiego in the late 1980s and early 1990s let alone people practising flying and golfing or solving puzzles on these computers as a spare-time activity.

There are those of us who still like to game on with our regular computers, be they desktops, all-in-ones or laptops or that they run Windows, MacOS X or Linux. This is although mobile devices like smartphones and tablets, along with games consoles of the XBox One and PS4 variety are being viable alternatives to the regular computer. Similarly, newer tablet and touchscreen-equipped convertible computers have been showing up, working under Windows 8.1 which is still considered a “regular-computer” operating system. This has extended to the likes of the Sony VAIO Tap 20 and its ilk which have a strong gaming appeal.

HP Envy X2 detachable-screen hybrid tablet-notebook computer – now to be a viable games machine

Of course, a significant amount of time on a regular computer is spent on various games whether they be conquering many worlds, setting up many empires, mimicking real life or engaging in car races or test flights. And I wouldn’t put it past flight attendants who work the long-haul flights to see these games being played on laptops through these flights.

But, unlike the games consoles and the mobile platforms where there is oversight through the companies behind these platforms, there hasn’t been a strong level of oversight when it comes to game quality. Some people have continued to raise issues about EA’s software quality especially in the light of the recent SimCity fiasco.

These “adaptive all-in-one” computers like the Sony VAIO Tap 20 are ending up as games machines

There have been a few quality-assurance programs out theire like the Microsoft “Games For Windows” program and Apple’s developer-assistance program for the Macintosh platform along with Valve’s Steam ecosystem. But the PC Gaming Alliance want to have a quality-assurance platform that is open and not bound to a particular developer in order to keep with the open nature of the regular-computing platforms.

One technical goal is to have a regular computer paint the graphics for a game to the 720p HD specification at 30 frames per second under load as a median requirement. This could allow the game to run on a modest processor like the Intel i5 processors which could typify a modest computer. Similarly, games titles that benefit from a console-style game controller as their user interface should benefit from these controllers and the games should take advantage of large-screen displays. The latter requirement would come in to its own with someone who wants to connect their laptop to a large-screen TV or projector to get the most out of their game.

Personally, I would like to see this apply across Windows, Macintosh and Linux builds of a game title so that no matter the platform, there is consistent software quality across the games. The companies representing these platforms could then be part of this alliance in order to encourage quality games development for their platforms.

Similarly, the games would have to be as though they are a part of the operating environment like what used to happen with Sierra’s and Broderbund’s output where these games worked smoothly with their host platform, exploiting what these platforms offered. It could also encompass network-game compatibility whether online or local-hosted and encompass multi-platform games where console players cam play alongside regular-computer or mobile-device players or play part of a game across different devices.

Could this be a chance for EA and others to lose their tarnished image when it comes to software quality for regular-computer gaming?

Festive season security myth: "If there are no links in an email, it can’t be a phish." | NakedSecurity Blog

My Comments

I have seen this happen as part of educating people about computer security is to think before you click. Here, it is about being careful about responding to emails and Websites of doubtful provenance so you don’t become a victim of a scam or find your computer full of malware.

For example, phishing scams initially used links in the email as a hook to get people to “verify” their accounts or take similar action. But they are now using “loaded” attachments with the copy of the email not having any links or HTML to avoid being rejected by security tools that are part of email clients or the populace not taking to the bait due to the public education about phishing scams.  The hook in these situations are the attachments that are crafted to take advantage of weaknesses in the software or carry links to Web resources as mentioned below.

PDF files represent their own dangers because they can either be crafted maliciously or contain links to Web resources. This is compounded by the problem that not all PDF reader software handles Web links in a manner similar to a Web browser. For example, a lot of these programs don’t show the URL when you hover over or dwell on the link before you click.

I would personally like to see PDF and similar document viewers support the ability to link with “website-reputation” engines like what Symantec and other security-software vendors offer and show graphics that indicate if a link you are hovering on is safe or not. Similarly, search engines, website reputation agents, security scanners and similar tools could also examine PDF files for abnormal construction and questionable links.

Instead, we have to do a “reality check” regarding these emails. For example, are the emails from a company whom you have had business with or part of ongoing business with that company? Are you expecting an email to come through with attachments? Do they contain a lot of poor spelling or grammar or aren’t commensurate to the language they are meant to be written in? Do they reflect the tone of what the business and its industry is about? Simply, does the context sound too “out of this world” to be real?

This also applies to any offers provided through instant-messaging or social-network channels including the Facebook “fake-event” scams that are popping up as I have mentioned before.

But for the moment, are you sure that the link or attachment you are to click on is kosher before you click on it?

SiliconDust (HDHomeRun)

HDHomeRun DUAL | Welcome to SiliconDust (Product Page)

My Comments

After SiliconDust have enabled the HDHomeRun Prime 3-tuner and 6-tuner cable-TV broadcast-LAN tuners with DLNA digital-media-server functionality for both standard and premium content, they have taken steps to bring this concept out to more of their range broadcast-LAN boxes.

Here, they are in the throes of issuing the HDHomeRun Dual broadcast-LAN box which has two tuners and is capable of picking over-the-air and unencrypted basic cable TV content and serving it over a home network. This is not just to their software or software that runs particular programming interfaces but to network video equipment that supports DLNA like the PS3 or an increasing number of Blu-Ray players and Smart TVs.

At the moment, as the retransmission fights take place between TV networks and cable companies about how much the cable operators pay the TV networks to package their content, we are starting to see the need for a regular TV antenna in most US homes to pick up the full complement of local TV content. This is even though it would have been available via the cable TV services. Similarly, the trend towards cord-cutting has brought American households back to traditional over-the-air TV alongside Netfilx and Hulu.

This device is intending to either complement the HDHomeRun Prime to bring in the over-the-air content  (including local channels lost to cable in-fighting) to the computers, smartphones, tablets and DLNA devices using the home network. Similarly, it would be an economy solution that could please the most persistent cord-cutter who occasionally dabbles in over-the-air for news and sport.

But what I see of this device is that it could be the start of action to port the DLNA capability to DVB-based HDHomeRun broadcast-LAN boxes that will end up in most of the rest of the world.

There will also have to be a time where SiliconDust and others who make DLNA-capable broadcast-LAN devices will need to factor in installations where multiple devices of this type are serving the same network at any time in the network’s life. This may be to increase concurrent viewing/recording capacity or to add coverage for particular broadcast bands and modes to an existing setup. Here, it may require the ability to have one logical tuner device representing multiple physical devices when it comes to broadcast-LAN content sources.
